GUS-QS0B-02-1691-BA Description

The GUS-QS0B-02-1691-BA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 1.69 kΩ resistance value per resistor with an ultra-tight 0.1% tolerance and a low ±50 ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a compact 20-pin QSOP package with gull-wing terminations, it offers a 1W total power rating (0.05W per resistor) and a maximum voltage rating of 100V. The device is non-automotive and non-PPAP compliant, making it ideal for industrial and commercial electronics where precision and reliability are critical.

GUS-QS0B-02-1691-BA Features

• Precision Thin Film Technology: Delivers ±0.1% tolerance and ±50 ppm/°C TCR for high-accuracy signal conditioning.
• Robust Construction: QSOP package (8.66 x 6.02 x 1.47 mm) with gull-wing leads for reliable surface-mount assembly.
• High Power Handling: 1W total dissipation (0.05W per resistor) with derated performance up to 125°C.
• Low Profile Design: 1.63 mm seated height suits space-constrained PCB layouts.
• Wide Voltage Range: Supports up to 100V, making it versatile for analog and digital circuits.
• Non-Compliant with EU RoHS: Suitable for legacy or specialized applications where RoHS exemptions apply.
